402 3D [Rotate] and [Copy]

There have many three-dimensional shape of the object in your brain that are wanted to share, but do not know how to express? How to "sketch" the three-dimensional image in your mind? 3D modeling technology can help us construct the most intuitive and understandable three-dimensional model. The use of floor plan interpret the three-dimensional object process－the most direct and effective expression of our ideas. We have designed many paradigms so that people can quickly understand the logic of using 3D CAD software Sketchup and drawing skills, from introduction to advanced, and introduce SketchUp 3D modeling technologies. After completing "3D CAD Fundamental", it is no longer difficult to draw ideas that are beyond imagination with 3D modeling technology! The goal of this course is to construct a three-dimensional model, with the computer as the main teaching material, to enrich the fun paradigm and the complete drawing process. Step-by-step teach you how to use Sketchup's 3D modeling software technology. With the completion of "3D CAD Fundamental", you will be able to realize the 3D objects that exist in the imagination through 3D modeling!

The third example, Beach ball is designed for learners to be familiar with [Circle], [Follow me], [Rotate] and [Paint Bucket]. Learners will understand how to draw a sphere using [Circle] and [Follow Me], how to use [Rotate] and [Copy] to draw the surface of the sphere and how to use selection tricks to delete all the unnecessary planes. The module also includes the methods of using [Paint bucket] to finish the beach ball.

Greetings to all. In today's class, we are going to learn how to manipulate and add details lies to spherical surfaces. Here, we will use new functions for the measurement box, which are important for next classes, so let's get started. After drawing the sphere, we want to divide the sphere surface equally. First, we make use of this flat surface. We double-click the surface to select the face and all its binding edges. Then right-click and choose Make Group. By grouping the surface, it will become easier while we work with it. Next, we want to make the sphere invisible. To do this, we go to Style Tools and then select Wireframe. With this action, we obtain a sphere displaying only the models lines. Next, we will rotate a surface and do copies. We select rotate tool on the toolbar or we can simply press Q. The rotate cursor will appear, then we find where we want to place the rotation center points. After finding rotation center points, would click and hold the left button of mouse. By doing so, we can change the direction of the rotation cursor. Change to the green axis or red axis. Here, we choose the red axis, then we click the green axis as origin. Make copies by pressing and releasing the control key. After this, we input 360 in the right bottom box and press Enter to rotate 360 degrees. Because we want to make 12 copies, so we input 12 followed by a slash in the measurement box. It means that we make 12 copies separated in 360 degrees. Then we switch back to the original style, then shade it, and we will obtain sphere divided into 12 parts. Today, we learn to draw over a spherical surface and create patterns on it. This will help us to finish the beach ball. Let's stop learning for now. Goodbye.
